The long term global is to hold the increase in the global average temperature to
well below 2°C above pre-industrial levels, and to pursue efforts to limit the temperature
increase to 1.5°C above pre-industrial levels, recognizing that this would significantly reduce
the risks and impacts of climate change.

In 2010, the COP agreed on a long-term global goal (LTGG) to reduce greenhouse gas
(GHG) emissions so as to hold the increase in global average temperature below 2°C above
pre-industrial levels.

The COP decided to periodically review: (1) the adequacy of this long-term global
goal in the light of the ultimate objective of the Convention, and
(2) overall progress toward achieving the long-term global goal, including a consideration of
the implementation of the commitments under the Convention.

In 2012, the COP decided to establish a structured expert dialogue
(SED) to support the review and to ensure scientific integrity through a focused exchange of
views, information and ideas. The final report on the SED is contained in
FCCC/SB/2015/INF.1

Parties, through Decision
10/CP.21on the 2013–2015 review, paragraph 4, decided in relation to
the long-term global goal, and in the light of the ultimate objective of the Convention that the long
term global is to hold the increase in the global average temperature to well below
2°C above pre-industrial levels, and to pursue efforts to limit the temperature increase to
1.5°C above pre-industrial levels, recognizing that this would significantly reduce the risks
and impacts of climate change. This is reflected in the Paris Agreement
(Decision
1/CP.21).

COP 21 requested the SBSTA and the SBI to consider the scope of the next periodic review with a
view to forwarding a recommendation for consideration by the COP by no later than 2018, as
appropriate. It agreed that the next periodic review should be conducted
in an effective and efficient manner, avoid duplication of work and take into account the results of
relevant work conducted under the Convention and its Kyoto Protocol and the subsidiary bodies.

Updates

In May 2016, at their forty-fourth sessions, the SBSTA and the SBI considered the scope of
the next periodic review, as mandated at COP 21 (see above). They noted the
relevant work on the global stocktake under the
APA, the facilitative dialogue, which will take place in 2018, and the technical
examination processes. They agreed to further consider the scope of the next periodic review at their
forty-sixth sessions (May 2017) and to refine it, taking into account relevant
experiences with the 2013–2015 review. The SBSTA and the SBI noted that an in-session
workshop on the scope of the next periodic review could be useful and that they may consider the
matter further at their forty-sixth sessions. The conclusions can be found in the respective
reports: SBSTA (page
14) and SBI
(page 26).

2013–2015 review

Information material

The 2013–2015 review considers various materials, including the IPCC assessment
reports

Submissions

Invitation for the submission of information and views from Parties addressing the
2013–2015 review

Outlook

The decision on the 2013-2015 review recognised that the first periodic review
fulfilled its mandate.

The SBI and
SBSTA are requested to consider the scope of the next review and forward a recommendation
for consideration by the COP no later than 2018. The SBSTA and SBI will further
consider the scope of the next periodic review at their forty-sixth sessions (May 2017). The
structured expert dialogue will be reconvened in conjunction with the next periodic review.
